It is Important to brand wine & spirit bottles in bars. Bars lose a lot of money as a result of bottle replacements. Dishonest staff replace sold bottles with others easily sourced else where.
To differentiate stock, and to help manage losses,
we have developed use of personalized adhesive bottle labels and/or heat shrink seals.
Labels ( Yellow ones ) are manually put on the bottle side.
Heat shrink seals ( BS ) are put on bottle necks using a heat gun machine.
